Came across this cool site (https://dfir.com/) that has some neat shirts.
Shirts for Men, Women, and also sells posters. That ship to the US.
My personal fav:
|Kudos for the Wolverine reference|
The site has written that "All proceeds go to Girls Who Code"
"We’re building the largest pipeline of future
female engineers in the United States."
Which looks like a awesome cause.
